| dc.description.abstract | 在這次的研究當中，使用有機敏化劑Rose Bengal做為敏化劑，合成三個蒽的衍生物MEPA(9-(2-mesitylethynyl)-10-phenylanthracene)、BMEPA (4,4’-bis[9-(2-mesitylethynyl)-10-phenylanthracene])、TPEPAN (9-(triphenyl)ethynyl-10-phenylanthracene)做為發光體，在四氫呋喃和甲醇混合溶液中研究上轉移現象。以568 nm激發Rose Bengal，在450 nm發現上轉移現象，為綠光轉藍光上轉移。在激發光與放出光之間的反斯托克斯位移(anti-stoke shift)的大小為0.57 eV (MEPA、BMEPA)與0.72 eV (TPEPAN )。然而，在此系統中，Rose Bengal也有部分的螢光放射，在這兩種波長的放射下，使我們可觀測到白光的產生。

| dc.description.abstract | In our research, we have synthesis three anthrancene derivatives MEPA (9-(2-mesitylethynyl)-10-phenylanthracene), BMEPA (4,4’-bis[9-(2-mesitylethy -nyl)-10-phenylanthracene]), TPEPAN (9- (triphenyl)ethynyl-10-phenylanthra- cene) as emitters. Up-conversion system has been investigated in THF/MeOH solution using Rose Bengal organic dye as a sensitizer. Upon excitation of Rose Bengal at 568nm, a blue up-converted emission at 450nm was observed. The anti-stoke shift between the energy of the exciting photons and emitted photons are ΔE≒0.57 eV(MEPA, BMEPA) and 0.72 eV (TPEPAN). However, the fluorescence of Rose Bengal was also observed in our systems. White light emission was therefore achieved as a result of the two types of synchronous luminescence.
